Jack Roush knows a thing or two about racing and Mustangs. His road racing career includes more than 110 wins and 20 national championships, and this vast expertise is evident throughout the ROUSH 427R Trak Pak.
Designed for the daily driver who enjoys pushing his car to the limits on open track days, the ROUSH 427R Trak Pak Mustang has plenty of specialized content to accommodate the unique needs of those who like driving up to the edge on the racetrack in a safe, controlled environment.
With the addition of the intercooled ROUSHcharger™ the 427R Trak Pak Mustang has 435 horsepower and 400 lb.-ft. of torque, plenty of power to quickly get up to speed on the straightaways. The cooling system has been enhanced with a black bar high flow front grille and radiator cooling shields. There is a functional strut tower brace under the hood to help strengthen the chassis and decrease unwanted twisting.
The suspension system has been completely revamped to easily manage the twists and turns of a road course. The ROUSH 427R Trak Pak suspension includes adjustable front and rear shocks, front and rear springs, front and rear stabilization bars, front and rear jounce bumpers and adjustable camber/caster plates.
To whoa this pony down ROUSH adds 6-piston front calipers with 14-inch, two-piece slotted front rotors and slotted rear rotors. The brake pads are replaced with high-performance racing quality versions, and the new ROUSH brake cooling system and high temperature brake fluid will ensure that the brakes will be ready when you need them the most.
The ROUSH three-piece aerobody kit gives the car a menacing look as it roars past the other cars on the track, and consists of a front fascia, front chin spoiler and hood scoop. The car rides on 18-inch forged wheels painted a dark charcoal and mounted to ultra-performance tires for maximum grip on the racetrack. The functional hood pins, unique graphics and badging add to the overall styling of the car.
Inside the cockpit the driver will immediately notice the addition of the new three-gauge dash pod with engine oil temperature, coolent temperature and a boost gauge. A shift light has also been integrated into this dash pod as well. The ROUSH sport leather seating, short throw shifter with retro-style ball, and four-piece performance pedal kit help to round out the interior styling.
